Square Mesh Open Area Calculation

Percent Open Area = 1- (Mesh Count x Wire Diameter)² X 100

EXAMPLE 1 40 x 40 Mesh, 0.010"

determine the open area of 40 Mesh, 0.010" Wire Diameter

• Multiply the Mesh Count x Wire Diameter.40 x 0.010 = 0.400
• Subtract the result above from 1.1 - 0.400 = 0.600
• Square the above result (multiply by itself).0.600 x 0.600 = 0.36
• Multiply the result by 100.100 x 0.36 = 36
• The solution should be expressed as as:36%

EXAMPLE 2 100 x 100 Mesh, 0.0045"

determine the open area of 100 Mesh, 0.0045" Wire Diameter

• Multiply the Mesh Count x Wire Diameter.100 x 0.0045 = 0.45
• Subtract the result above from 1.1 - 0.450 = 0.55
• Square the above result (multiply by itself).0.55 x 0.55 = 0.3025
• Multiply the result by 100.100 x 0.3025 = 30.25
• The solution should be expressed as as:30.25%
